linux下挂盘

1、首先，查看磁盘，fdisk -l

Disk /dev/xvdf: 536.9 GB,  bytes,  sectors
Units = sectors of  *  =  bytes
Sector size (logical/physical):  bytes /  bytes
I/O size (minimum/optimal):  bytes /  bytes

2、进入磁盘，对磁盘进行分区

[root@shap000103262 ~]# fdisk /dev/xvdf
Welcome to fdisk (util-linux 2.23.).

Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.

Device does not contain a recognized partition table
Building a new DOS disklabel with disk identifier 0x9c0f9ab7.

Command (m for help): n
Partition type:
   p   primary ( primary,  extended,  free)
   e   extended
Select (default p): p
Partition number (-, default ):
First sector (-, default ):
Using default value
Last sector, +sectors or +size{K,M,G} (-, default ):
Using default value
Partition  of type Linux and of size  GiB is set

Command (m for help): w

3、格式化分区

[root@shap000103262 ~]# mkfs.ext3 /dev/xvdf1
mke2fs 1.42. (-Dec-)
Filesystem label=
OS type: Linux
Block size= (log=)
Fragment size= (log=)
Stride= blocks, Stripe width= blocks
 inodes,  blocks
 blocks (5.00%) reserved for the super user
First data block=
Maximum filesystem blocks=
 block groups
 blocks per group,  fragments per group
 inodes per group
Superblock backups stored on blocks:
    , , , , , , , , ,
    , , , , , , , 

Allocating group tables: done
Writing inode tables: done
Creating journal ( blocks): done

4、开始挂载分区

mount  /dev/xvdf1 /opt/share
